Question about Whirlpool LER4634J Electric Dryer

Overheating & Cutting Off

Have Whirlpool LER4634EQ2 dryer. Runs for just a few moments and shuts off and appears to be overheating. Have cleaned entire exhaust path spotless. Airflow through the vent outside is very good. Bin is tumbling and fan is blowing.

I saw other suggested solutions that all said the airflow path has to be clean. I am sure this one is.

Thanks for any help anyone can provide.

    My dryer will start up for 15 seconds and turn off. Five minutes later it will turn on again for 30 seconds and then off for a while. There is a slight burning/electrical smell behind the dryer. What could be causing this?

    Everything else seems to be running fine. The drum turns, heat and the blower are produced while its running. Any advice on anything to check would be wonderful! I would like to have some dry clothes!

    I tried the replacing TIB device (Whirlpool part#3387134). Ran the dryer with some clothes, and it had the same issue. It would work then shut off, work then shut off. Any other recommendations?

Ok, this sounds like it could be what is know as your machine's "Thermal Internal Bias" (TIB) device (Whirlpool part #: 3387134). It's @ $15 I think and easily accessed by removing the rear panel of the dryer. It is attached to the blower housing located on the lower left as your are facing the dryer.

It's designed to "cut-out" if the dryer temp is too great at the blower. After the air cools a bit it comes the dryer contines operating. Your TIB my be getting weak and not so hardy as to tolerate the high temps. Replace and give it a try.

Remember to unplug your dryer before attempting this! Safety first and always!

I ran into the same issue. I know this is an older post, but in case anyone else comes across it there is a thermal fuse, located just above the Thermal Internal Bias. The part number is 3392519 and it is called Thermal Fuse.

What is wrong with a whirlpool 4 cycles 3 temperature dryer that will not get hot?


First clean the vents inside the dryer and to the outside be sure and clean around the blower wheel. Check the thermal fuse, the cutout fuse & all the thermostats. Check the heating element also check that it is not grounded to the heater box. Last check the centrifical switch on the motor as the heater runs through it.
Hope this will help you

I have a whirlpool dryer that won't stay running. It starts and runs for awhile and then shuts off. If you wait awhile you can start it again. The model number is WGD6400SW. It's a gas dryer.


It may be overheating. Make sure it is able to vent and that all fluff filters and vents (and any fluff you can see) are cleaned and there are no blockages. If it continues it will need to be serviced/checked.
I hope I have been of help but please do not hesitate to ask if you have any further questions.
I appreciate your vote if you appreciate my reply.

Dryer runs for awhile then shuts down while still having time left on the timer


it is possible that it is overheating and the internal tem sensor is shutting down. Excvess lint can cause this and it needs serice intervention to do this unless you know how to clean the lint filter.
It has the potential to catch fire if the sensor fails sometime and the unit runs on overheating to the point of becoming flammable

If your dryer stops during its cycle, wait ten minutes and start dryer again. If dryer starts, then the motor was overheating.

Solution, Check for lint blockage around the motor and for possible overloading. If dryer repeatedly stops during its cycle, especially during consecutive loads, replace motor.

Good luck
